I'm not sure I fully understand the question. Are you attempting to convert all pixels with RGB value 72, 255, 25 to white? Or are you trying to scale the image to 8-bit? <div><br></div><div>Sounds like the former. In this case -scale is not the way to go. I'm honestly not sure what is, short of reading each band into a numpy array and then checking individual pixels in each band. You could then modify the value in each array by position.<br>
